Commands Module

ShellOperation

A block representing a shell operation, containing multiple commands.

For long-lasting operations, use the trigger method and utilize the block as a context manager for automatic closure of processes when context is exited. If not, manually call the close method to close processes.

For short-lasting operations, use the run method. Context is automatically managed with this method.

To load the ShellOperation:

from prefect import flow
from prefect_shell.commands import ShellOperation

@flow
def my_flow():
    my_block = ShellOperation.load("block-name")

my_flow()
